BICYCLE-RIM.

To all whom it may concern."

Be it known that I, ARTHUR C. BAILEY; a resident of the city of Vancouver, in the county of C ark and State of Washington,

have. invented a new and useful Bicycle- Bim, of which tion. I v

My invention relates more particularly to a rim such as is used on bicycles, and to a means for securing same to'the tires.

The object of my invention is to provide an exceedingly simple and efficient means for attaching and looking a rubber tire to a rim, and at the same time provide an exceedingly strong rim incapable of being affected by heat or moisture.

I attain these results in the manner illustrated in the accompanying drawing and described in the specification following.

Referring to the drawing. Figure l is a plan view of the rim showing the manner the folloiiing is a specificain which it is united to the tire, portions of the-rim and tire being cut away for clearness; Fig. 2 IS aclrcumferential View of the r1m member; Fg. 3 is an enlarged sectlonal 1 view through the tire and the locking means;

Fig. 4 is a side elevation of Fig. 3.

Similar letters and numbers of reference refer to the same or similar out the several views.

' Referring in detail to the drawing. R? is the inside portionof the rim of Which R forms the outside and R the latteral edges, R is the hollow portion between the inside wall R and the outside wall R Iare openings in the inner wall R for the sbokes. The holes R are formed in the outside wall R and are somewhat larger than the holes R in order that they may permit the heads of the spoke nipples topass through thehole R, but preventing them from passing through the hole R The holes R are also in prolongation of the spokes and occupy positions preferably between the holes R. The holes R are elongated and narrowed at the ends R for purposes which will be explained later on. R are shanks of ordi- Specification of Letters Patent.

nary spoke nipples on which are formed the V heads R and which engage the spokes Ru.

The narrow ends R of the elongated holes R are turned back at R in order that they may'form a -blunt edge and thereby avoid having the rim destroydts own locking device by a cutting action.

While I have thus illustrated and de U scribed my invention it is not my intention to limit myself to this precise form or method of application, but intend that it shall cover all forms and modifications that fall fairly"'within the appended claim.

What I claim as new and desire to protect by Letters Patentof the United States, is:

A metal bicycle rim having a hollow cross section in combination with a tire, said hollow portion being adapted to contain heads of spoke nipples as well as. heads of mi 1- room shaped buttons which project from the inner periphery ofthe tire, said rim having elongated'openi-ngs formed in its outer sur-.

face, each opening having one end large enough to admit the head of a button, and the opposite end being adapted to engage the neck of said button and having a blunt edge at the end of said button engaging portion of said elongated hole which is adapted to prevent any cutting action by the rim "against said button neck.
